Welcome to Canada, and thank you for your question!
In most cases, the use of "less" with a plural noun is considered an error in Canada (just as it is elsewhere in the English-speaking world). The exception: measurements that are plural in form but express a singular idea. For details, see our tip on the correct use of "less" and "fewer": https://www.noslangues-ourlanguages.gc.ca/en/writing-tips-plus/fewer-less-lesser.
